native collector, and recorded his captures daily in my journal. 

 There was no sweet water in Karachi then, and but very few and 

 feeble attempts at gardening— little but saud everywhere, and conse- 

 quently the Lepidopterous fauna was verv limited, and mainly 

 limited, as might be expected, to desert forms. 



With the introduction of the Mulleer Water Works the whole face of 

 Karachi is rapidly changing — gardens are springing up everywhere, 

 all kinds of new trees are being cultivated, and this change is bring- 

 ing a number of fresh species of butterflies and moths into the neigh- 

 bourhood. I received a number of new things from Mr. Murray in 

 1882, after an unusually heavy rainfall, and during my stay there 

 from the 30th March 1885 to 21st September 1886, I captured many 

 more fresh species, and I now purpose giving a complete list of all 

 the lepidoptera within my knowledge taken at Karachi and its 

 vicinity up to date. 



The list of species is still very limited ; it will no doubt go on 

 increasing every year with the growth of vegetation* until it some- 

 what resembles that of Bombay, but in consequence of the sandy 

 nature of its surroundings, Karachi will always contain many desert 

 species, and will lack many of the species which thrive in the moist 

 atmosphere of the Bombay coast. For instance, the genus Isias, so 

 plentifully represented in Bombay, is entirely absent from Karachi; 

 as also the eucharis group of the genus Callosune, very abundant 

 in Bombay, is nowhere to be seen about Kaiachi, whereas, on the 

 other hand, the dulcis group of the same genus, and xhedynamene 

 group of the sub-genus Idmais to.be met with in abundance in one 

 or other of its species all the year through at Karachi, are only repre- 

 sented in Bombay by very rare specimens of Callosune taflini 

 Swinhoe, and Idmais cyjiroea^ Fabr.
